Our will, through our own choosing, is good when it operates from reason and duty alone. In this way, the Categorical Imperative guides us to being truly moral. Further, freedom is the ability to be motivated by your own choices, and to be able to deliberate and act on reason. So why be moral? Because it is a pure extension of our autonomy – and there is nothing greater than freedom.
In his book Metaphysics of Morals, Kant expresses that neither state, nor society can exist without laws. Kant’s view on crime and punishment is as follows:
“If there is no law, there is no society and no state. Therefore enforcement of the of the law, which is the society’s foundation, means protection of the society and the state. Thus, any person violating the law loses the right to be a society member and consequently must be deemed guilty and punished.”
